About this 1.78ct lab-grown emerald diamond

This 1.78ct lab-grown emerald sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836603451 or 836603451. Listed at 12 retailers as of October 29, 2026, with prices from $858 to $5,700, a $4,842 spread on the same certified stone. Brilliant Earth lists it at $5,700. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
